I applied online. The process took 4 weeks. I interviewed at Ansys in Nov 2022
Interview
There are three stages in the interview process, you first meet with HR, they ask some questions thats aimed to get to know you, then you have a 1hr meeting with the manager where he ask you very technical questions. Lastly you take a technical quiz (85 MCQs).
Interview questions [1]
Question 1
they were mainly multiple choice questions that had to do with algorithms, data strucutures and some more level of difficulty like Multiprocessing etc.
I was asked 2-4 leetcode style questions (ranging from easy-medium in difficulty) including time complexity, etc. Questions seemed more math/algorithm oriented. Also asked about work experience, previous internships, soft skills, etc. Heard back in about a week iirc.
Hour long technical interview with four engineers. Prepare your data structures and algorithms. Know your language in and out. Be kind, be friendly, and be smart. Good luck in your endeavors.
